In this video, see how AdBlue plays an important role in reducing nitrogen oxide emissions in vehicles equipped with SCR catalysts. It is crucial to monitor the level of the dedicated tank, as a low level would prevent the vehicle from starting.

To check the amount of fluid present, sit in the driver's seat of the Mercedes GLC, turn on the ignition, use the controls on the right side of the steering wheel, press the Home button, and using the touch interface, select the "service" menu. Choose "adblue" to view both the level and the distance you can drive.
